PixelSearch region check addition to code, how??

[reese646]

Right I've had a good time this morning, and my first post resulted in a great solution to an alarm for changes to a region, I have tidied that thread up and marked it as solved as the questions I was additionally asking we're going of the original topic and I only have one more message left today? (any help on getting aditional messages would be appreciated).
 
Anyway Ive took this code.

; Provide a way to exit
HotKeySet("{+}", "On_Exit") ;uses the + key to exit the program

; Get an initial checksum
$nCurr_Checksum = PixelChecksum(0, 0, 400, 400);alter this region to the region requiring monitoring

; Start the loop
While 1
    ; Get a new checksum
    $nNew_Checksum = PixelChecksum(0, 0, 400, 400) ;alter this to match the PixelCheckSum above
    ; See if the area has changed
    If $nNew_Checksum <> $nCurr_Checksum Then
        ; If so then notify
        SoundPlay(@WindowsDir & "\Media\notify.wav", 1) ;\media\notify.wav can be changed to any other audible file
        ConsoleWrite("!Changed" & @CRLF)
        ; And reset the checksum to check against next time round
        $nCurr_Checksum = $nNew_Checksum
    EndIf
    ; Wait 1 sec and do it all again
    Sleep(400) ;in milliseconds altering this changes how quickly the script refreshes
WEnd

Func On_Exit()
    Exit
EndFunc

this provides an alarm for an area should it change, and resets once the alarm has sounded.

The problem is transparency, the messenger window I'm monitoring has a transparency so things behind it are setting off the alarm, so I believe I need to add a PixelSearch to the code, have tried a few and getting errors, tried this and no errors, but no alarm, and help appreciated.

; Provide a way to exit
HotKeySet("{+}", "On_Exit") ;uses the + key to exit the program

; Get an initial checksum
$nCurr_Checksum = PixelChecksum(2129, 448, 2220, 1200);alter this region to the region requiring monitoring

; Start the loop
While 1
    ; Get a new checksum
    $nNew_Checksum = PixelChecksum(2129, 448, 2220, 1200) ;alter this to match the PixelCheckSum above
    ; See if the area has changed
    If $nNew_Checksum <> $nCurr_Checksum And PixelSearch (2129, 448, 2220, 1200, 0x252424 ,2 ) Then
        ; If so then notify
        SoundPlay(@WindowsDir & "\Media\notify.wav", 1) ;\media\notify.wav can be changed to any other audible file
        ConsoleWrite("!Changed" & @CRLF)
        ; And reset the checksum to check against next time round
        $nCurr_Checksum = $nNew_Checksum
    EndIf
    ; Wait 1 sec and do it all again
    Sleep(400) ;in milliseconds altering this changes how quickly the script refreshes
WEnd

Func On_Exit()
    Exit
EndFunc

reese646,

I have lifted your "New Member" posting restriction.

Now I will look at your question.

Edit:

I am not at all sure that PixelSearch is going to help here if the background is changing and affecting teh colours in an area. Some screenshots of the messenger window before and after a "real" notification and when the background is "changing" between these 2 points would be a great help. We might be able to identify something more specific that you can use to indicate the "real" change.

Also, is it possible to hook into the control on the window in question to see if something has changed? That method would be MUCH more stable.

hi, just checking back in on the fly so can't sort any pictures out at the minute, as asked about the change in colour I'd say the transparency is only 5-8 percent and so is only very mildly affecting the base colour as a light shimmer if you know what I mean, similar I suppose to windows aero transparency, but this very slight pixel tinting is enough obviously to give a false positive, hence my thinking that if a pixelsearch could be implemented after the pixelchecksum as a secondary condition then it would solve the problem, implementing it is the current problem, changing the colour variation in the pixelsearch variables is something I can play with once I've got something to work with.

Have tried a few things and worked my way through some of the tutorials and its really interesting, but I'm struggling to apply this knowledge so far to the problem in  hand.

Many thanks

reese646,

Another thought - how about putting a non-transparent window underneath the messenger GUI? That way you can prevent the background from showing through. It is quite easy to get an AutoIt GUI to "follow" another so that you do not have to keep the messenger window in a fixed position.
